Scarlet Elgueta

Postdoctoral Researcher at USACH

Former Postdoctoral Researcher at the IEA

I am currently a Postdoctoral Researcher at Universidad de Santiago de Chile (USACH). I worked formerly at IEA-UDP as a Postdoctoral Researcher in the group of Paula Jofré. I specialize in infrared spectroscopy.

Projects

My primary goal is to recalibrate atomic information related to the absorption lines observed in the spectrum of stars. This allows for a differential analysis approach, providing accurate and precise measurements of chemical abundances. Most of my work involves working with CRIRES+ and WINERED spectra obtained from different types of astrophysical objects. I study a wide range of subjects, from the crucial Gaia Benchmark Stars (GBS) to Type II Cepheids in the Bulge region. Additionally, I have a strong interest in investigating n-capture elements in the infrared regime, as they provide valuable insights into the chemical evolution of our Galaxy.

Highlights

I’m a member of the WINERED collaboration and the GBS collaboration. As a result of my research project with WINERED spectra, I recently released the results of my analysis of the time-series spectra of classical Cepheids where their atomic information was recalibrated in order to obtain consistent abundance with the optical, this can be found in Elgueta et al. 2024.
